The authors analyzed data from 15 patients with idiopathic dilated cardiomyopathy to evaluate the hemodynamic changes and left ventricular cineangiogram as compared with normal control. Mean right atrial pressure, right ventricular systolic pressure, mean pulmonary artery pressure and mean pulmonary wedge pressure were signigicantly elevated in patients with dilated cardiomyopathy. Left ventricular enddiastolic volume was increased in idiopathic dilated cardiomyopathy(139.9+/-58.73 ml/m2). Cardiac index, left ventricular ejection fraction and circumferential fiber shortening were significantly reduced in patients with dilated cardiomyopathy as compared with normal control(p<0.001). Hypokinetic, diffuse wall motion abnormalities of left ventricle were common in idiopathic dilated cardiomyopathy. A few cases of akinetic or dyskinetic segmental wall motion abnormalities were present. Left ventricular configurations in patients with idiopathic dilated cardiomyopathy were globe shape(53.4%) as compared with pear core shape(90%) of normal control. Associated mitral regurgitations in patients with idiopathic dilated cardiomyopathy confirmed by left ventricular cineangiogram were 53.3 percent. Mild to moderate mitral regurgitations were often present(46.6%).

Despite the progress in the treament of the subretinal neovascular membrane(SRNVM) by the development of laser photocoagulation, it has been reported difficult to manage with laser photocoagu1ation on which developed in high myopic eyes: first, their location in relation to the foveola is usually difficult to discriminate; second, subretinal neovascular m6mbrane developes very close to the foveola; third, the atrophic photocoagulation scar may extend to the foveola. The interferone alpha 2a has been known to suppress angiogenetic activity, and its application to subretinal neovascular membrane in high myopia has been suggested. The effect of interferon alpha 2a on neovascular membrane in high myopia was investigated by the authors. Subjects included 16 eyes with interferon treament and 12 eyes as control who had been followed for 3 months or longer. The median total dose in these patients was 75 X 10(6) units, given over a six- to eight-week period. In the interferon treament group, the activity of neovascular membrane decreased in 9 eyes(56%) and the visual acuity improved in 7 eyes(44%). In contrast, the control group showed a sustained activity of neovascular membrane and the visual acuity was improved in only one eye(6%). Therefore, interferon alpha 2a can be considered as an alternative method in the management of the some subretinal neovascualr membrane in high myopia which is resistant to the other treament.

PURPOSE: Lower urinary tract symptom in elderly person leads to their psychological anxiety and stress in their travel and further, loss of self esteem that can set limitation during their social activities and their lives. we coined a frequency-anxiety syndrome (FAS) for the patients with lower urinary tract symptom and anxiety. This study was performed to characterize the clinical characteristics of FAS. MATERIALS AND METHODS: 24 FAS patients and 20 controls were included in this study. For the analysis and comparisons, we investigated frequency, urgency, i-nternational prostate symptom score (I-PSS), cystoscopy, and urodynamic study in both groups. We also performed semi-structured psychiatric interview and state-Trait Anxiety Inventory (STAI). RESULTS: In the average I-PSS, FAS group had significantly higher score of 22.9+/-10.9 than control group of 10.6+/-6.5 (p<0.001). The control group had significantly higher quality of life herving problems (QOL) value of 1.8+/-1.2 as compared to FAS group of 5.1+/-0.1 (p<0.005). In STAI, FAS group had significantiy higher score than control group. CONCLUSIONS: There were significant differences between FAS group and control group in regard to lower urinary tract symptom, I-PSS, QOL, and anxiety. The above results suggest that FAS could be considered as independent syndrome.

Vitreous surgery has become a widly practiced procedure for use in the variety of pathological conditions in the anterior and posterior semgment of the eye. The goal of the vitreous 'surgery is to clear the optic pathway and restore the anatomy and function of the eye. Vitreous surgery was performed in 28 eyes using the O'malley ocutome from April, 1980 to October, 1980. Among the 28 eyes, 14 eyes received anterior segment surgery and the other 14 eyes received posterior segment surgery. The follow up period after surgery ranged from 3 weeks to 7 months and the average period was 4 months. The conditions requiring surgery were as follows: 9 eyes had Reconstruction of anterior segment after trauma; 4, removal of pupillary membrane due to chronic uveitis and after cataract; and 1, anterior vitrectomy with removal of subluxated lens. As for the causes of posterior segment surgery, 5 eyes had trauma of eyeballs; 3, hypertensive retinopathies; 2, vitreous opacity with retinal detachment; 1, diabetic retinopathy; 1, central retinal vein occlusion; 1, nonmagnetic intraocular foreignbody; and 1, lost lens nucleus into the vitreous. The improvement of visual acuity after surgery was seen in 14 eyes (50%), 9 eyes in anterior segment surgery and 5 eyes in posterior segment surgery. The complications during operation were vitreous hemorrhage (1 eye; 3.5%), retinal detachment (2 eye; 7%), and traumatic cataract (1 eye; 3.5%). Postoperative complications were phthisis bulbi (1 eye; 3.5%), and cataract (1 ; 3.5%). We found that vitreous surgery is not only useful to removal of the various pathologic conditions of vitreous through the pars plana approach but in anterior segment as an emergency procedure at the time of trauma and vitreous loss during anterior segment surgery.

Merkel cell carcinoma (MCC) is an unusual primary cutaneous tumor, occasionally found con-current with other malignancies. A case of MCC with coexisting squamous cell carcinoma (SCC) was studied histologically, immunohistochemically and ultrastructurally. The MCC and SCC occured at the same site, but each preserved its identity and transition between the two was not identified.

The coronary artery cross sectional area (CSA) is proportional to LV mass. We have measured the cross sectional area of the left and right coronary arteries in patients with ischemic heart disease to see whether it is related to the change in the LV mass. The following results were obtained ; 1) There were no significant difference in mean CSA of coronary arteries and LV mass determined by echocardiography and cineangiography between control and ischemic heart disease. 2) There were significantly increased ratio of left ventricular mass by cineangiogram to CSA of left anterior descending coronary artery in patients with myocardial infarction as compared with control group. 3) A linear relation between LV mass by cineangiogram and CSA of left coronary artery was noted in control group (r=0.53, P<0.05) and ischemic heart disease group (r=0.51, P<0.05). 4) A linear relation between LV mass determined by echocardiography and CSA of left coronary artery was noted in control group (r=0.55, P<0.05).

After the intraocular bleeding was inuced by amputation of the rabbit retinal artery, the level and duration of the level of the intraocular pressure to control the bleeding was studied. Then, the eyes were enucleated and evaluated for the effect of the increased intraocular pressure. In 3 of 4 eyes studied, the bleeding is controlled at the height of 140-145 cm of the infusion bottle for 10 seconds. And the maintenance of the height of 125 cm for 15 seconds was effective in one eye. Although the expanded intercellular space in the outer nuclear layer, destruction of the photoreceptors and formation of the vacuoles appeared in the first week, they were only the temporary findings for they disappeared after second week. In the rebbit, the retinal arterial bleeding is able to be controlled at the level of about 100 mmHg of the IOP for about 10 seconds effectively and safely.
